TC358766 Display Bridge for DisplayPort™

Connectivity

D2DP

Description

The Toshiba TC358766 display bridge is optimized for

handheld devices using a Host Processor with Mobile

Industry Processor Interface (MIPI) Display Serial

Interface (DSI) or Display Pixel Interface (DPI)

connectivity. The TC358766 functions as a protocol

bridge enabling the video stream from the Host

Processor DSI link or DPI link to drive a single or two

independent DisplayPort panel(s). The TC358766 has

a DSI receiver that can be configured to support up to

four DSI lanes with data rates up to 1 Gbps per lane,

for maximum total bandwidth of 4 Gbps. It also has a

DPI receiver that can be configured to support 16, 18 or

24 bits parallel interfaces and can be operated up to

154 MHz parallel clock. The DisplayPort transmitter can

be configured to support a single Main Link with one or

2 lanes or dual Main Links with single lane per link. The

data throughput is 1.62 Gbps or 2.7 Gbps per lane of

the DisplayPort Main Link.

As the DisplayPort interface uses fewer lines and

power consumption is more efficient, availability and

usage of highresolution DisplayPort panels is becoming

a feature in handheld applications such as tablets and

netbooks. The Toshiba TC358766 display bridge can

support displays with resolution up to 1920 x 1200

(WUXGA) at 24 bits per pixel, at refresh rate of 60

frames per second. The TC358766 can support both an

embedded DisplayPort panel (eDP) or an external DP

panel at one time or simultaneously. The TC358766

bridge supports audio streaming from the Application

Processor through the I

transmitted through the DisplayPort link if the

application requires, i.e. connecting to an external

panel.

The TC358766 is a 120-pin device, in a small package

size of 6 mm x 6 mm, 0.50 mm ball pitch designed for

portable products.

Highlights
